A fuel distributor rail for a fuel injection system for an internal combustion engine in motor vehicles, in particular for gasoline engines. The fuel distributor rail comprises a main tube, wherein the main tube has a fuel channel extending in the longitudinal direction of the main tube. The main tube comprises at least two outlet openings, wherein the outlet openings branch off the fuel channel. A connecting element is arranged on the main tube, wherein the connecting element has an attachment wall that rests against the main tube. The connecting element is connected to the main tube in a material bonded manner and comprises at least two connecting pieces. The connecting pieces have a connecting channel each for the fluidic connection of an outlet opening to each injection nozzle.

A monolithic fuel delivery system for gasoline direct injection to an engine. The system has a common rail tube body from which injector sockets smoothly and seamlessly extend. Uninterrupted junctions are formed between the rail tube body and the injector sockets. The seamless junctions present a sealed relationship between the tube body and the injector sockets.

A method for repairing damage to a fuel pump assembly of a locomotive is provided that includes identifying a void within a fluid cavity of a fuel pump assembly. After identifying the void within the fluid cavity of the fuel pump assembly, the void is cleaned with a cleaning product, and a filler material is inserted within the void. Then the filler material is laser welded to repair the void. After being laser welded, the fluid cavity of the fuel pump assembly is honed.

A coil assembly in a fuel injector includes a magnetic core and; a winding wound around the core, the winding being overmoulded and forming a cylindrical overmoulding. An axial blind hole extends towards the interior of the coil assembly from a first surface to a distal end, the blind hole being suitable for housing at least one spring for loading a magnetic armature. The coil assembly is provided with a degassing hole passing through the core and the overmoulding from the blind axial hole to an axial outer cylindrical surface, the degassing hole being provided in the magnetic core and having a restriction that is arranged in a first section that is proximal to the blind axial hole.

A fluid passage device including a passage for flowing high-pressure fluid of a predetermined or higher pressure comprises a sac bore cylinder of a metal, which includes therein a closed passage and a branch passage. The closed passage is shaped to extend straightly in a predetermined direction and has a closed top end, and the branch passage is branched off from the closed passage. A top end part of the closed passage at a closed side is defined by a ceiling wall surface, which is perpendicular to the predetermined direction, a passage wall surface, which is parallel to the predetermined direction, and a connecting wall surface, which connects the ceiling wall surface and the passage wall surface. The connecting wall surface is shaped to curve in a direction to expand the closed passage.
